IMPRQVEMENT IN HEATlNG-STOVES.`

l The Schedule referred to in these Letters Patent and making part of the same To all whom et may concern Be it'known that I, WILLIAM MAGILL, of Portof the same, reference -being had to the accompanying drawing making a part of this specification, in which- Figure l is a sectional elevation;

Figure '2 is a horizontal section in the line a; a', lig. l; and Y Figure is a' horizontal section in the line y y, fig. 1. This invention has for its object the burning of fuel, and all the smoke that arises therefrom-within the stove, in order that the greatest possible amount of heat may be generated, and turned to account in warming apartments, with the least possible waste, this end being accomplished bycausing the smoke that rises through the magazine to moet a current ot' cold air, and be thereby turned backward and carried again through the tire-chamber, undergoing therein a second combustion.

In the drawinga is the fire-chamber of a base-burning stove;

b, the ash-chamber beneath and o, the magazine above the fire-chamber, said magazine being of the usual funnel-shape, and hung by a flange at its'upper end upon a ilange projecting inwardly from the lower end of a cylinder, d, that rests in a funnel-shapedv flange, e, which projects downward, and inward from 'the lower end of a cylinder, f, that is placed within the outer shell 71, which is supported upon the ring t' that contains tlze micawindows, the -cylinders d and f being sustained by legs k, whichrest on the ledge l of thepcdestal. ot the stove.

A covered cylinder, g, provided with internal vcrtical ribs, is supported upon the cylinder d, standing oti between the latter and the cylinderj, the bottom ot' the cylinder g not being in contact with the inside of the tapering flange e, and the cover of the cylinder g not being in contact with the top of the inside cylinder d, but spaces being provided whereby smoke, rising through said inside cylinder, may pass over the top of the latter, pass downward between it and the intermediate cylinder g, and escape past the bottom of the latter into the space between it and the outer cylinder jl v In the cover of the cylinder y is a hood, j, in front ot which is a chute, m, through which coal passes. to the magazine.

A vertical door, n, is hung within the hoedj, so

as to close the space between it and the chute,'for the purpose of preventing the escape ot" smoke, which door is self-closing.

A ring, o, surrounds the Lipper part of the cylinder j.

On the ring o is constructed a cap, 1), having a tal guard, r, and vertical converging guards, s, at lthe sides, overlapping similar guards t that extend from the sides of the hood j, the function of all which guards .is to prevent coal from lodging on the cover of the cylinder g. Y

rIhe cap 1) is also provided with an inclined plate, Au, that 'slants toward the chute m. In the inclosing shell h is a charging-door, fv, directly opposite. theI opening q, and, in the opposite side of the shell from the charging-door, is the ue w, by which gases' escape into thechimney.

When a ire is building in the chamber a, the door c and its register should be closed, and the sliding doors of the ash-chamber 11, beneath the lirechamber, opened. This creates aY draught directly from the ash-doors, through the fire-chamber and magazineand up between the inclosing shell hand cylinder f to the ue w.

The fire Vhaving been built, the ash-doors should be closed, and the register in the charging-door c opened.

Cold air`thereupon enters through vthe register, and passes through thc opening q iu the cap p under the guard fr and inclined plate u, over the guards t and hood j, and down 'in to the'space x, between the cylinders f and y.

The legs 7.-., on which the cylinder j is supported,

are hollow, and open at their upper ends into said" space, and-at-tl-ieir lower ends they communicate with orifices in -the ledge l.

The cold air, whose course has been traced as far as the space x, iiows downward throughthe ilues k, and passes beneath the hre-chamber a.

As this is 'the only air with which the stove is now supplied, it creates a draught within the space x, which draws the smoke from the fire-chamber up through the magazine and cylinder 11, over the top of the latter, and downward between it and the cylinder g, into the space Here, meeting the cold current of air above mentioned, the smoke. isV drawn by the 'latter downward through the tlues 7s, and, in company with such current, it passes upward through the grate at the bottom of' the hre-chamber, andvis subject to a conibustion while rising through the latter, which nearly or quite consumes it.

Having thusdescribed my invention,

That I claim as new, and desire .to secure by Letters Patent, is-

l. The hanging, self-closing doorn, hood j, chute mf, and cylinder g, all arranged as specified.

2. The cap' p, provided with the opening g and guards r and s, and the cylinder g, provided with the hood j and guards t, arranged together as described. i

3. The cylinders d f g, iiues le, magazine c, and fire-chamber a, arranged together as set forth.
